THEODORE REMLINGER, OF ELIZABETH, NEW JERSEY.

PAIDLOCK.

To all whom it may concern.

Be it known that I, Ti-rnononn REMLINGER, a subject of the Czar ofRussia, residing at Elizabeth, in the county of Union and State of NewJersey, have invented. certain Improvements in Padlocks, of which thefollowing is a specification.

The objects of this invention are to provide a padlock which shall bedifficult of opening by unauthorized persons; to provide means besidesthe key means for giving added security; to obtain a novel and improvedconstruction of such a padlock, and to secure other advantages andresults as may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals ofreference indicate corresponding parts in each of the several figures,Figure 1 is a view in elevation of my improved padlock from the keyside, locked and with the key-hole doors closed; Fig. 2 is an edge viewof the same; Fig. 3 is a side view of a portion of the padlock, showingthe keyhole doors open; Fig. 4 is a View similar to that shown in Fig.1, with the front wall of the padlock removed; Fig. 5 is a view similarto that shown in Fig. 4, with a certain slide plate and parts carriedthereby removed; Fig. 6 is a section taken on line 66 of Fig. 4, or justabove the lock bolt, the keyhole doors being open; Fig. 7 is a sectionon line 7-7 of Fig. 1; Fig. 8 is a section taken on line 88 of Fig. 4,and Fig. 9 is a detail section on line 9-9, Fig. 5, looking in thedirection indicated by the arrow.

In said drawings, 10 indicates the front wall of the padlock, or wallhaving the keyhole 39, and 11 is the opposite or back wall. 12 indicatesthe edge wall of the padlock, standing edgewise between said walls 10,11, and held thereto by stays 13 riveted into all three parts, as shownin Fig. 9.

14 indicates the top wall of the padlock, beneath the shackle 17, andwhich top wall is shown as a separate piece from the edge wall 12,although it might be integral therewith. This top wall has edge lugs 15riveted into the side walls 10, 11 of the padlock to hold it in place,and at one end bends downward, as at 16, and is apertured to provide aslideway or bearing for the tongue 20 of the lock bolt 21. The shackle17 is hinged, as at 18, between the front and back walls 10, 11 of thepadlock, and at its other end Specification of Letters Patent.

Serial No. 536,132.

has an apertured extremity 19 to enter the padlock chamber 22 andreceive the tongue 20 of the lock bolt. The body 21 of the lock boltlies flat against the back wall 11 of the padlock and is slotted, as at23, to slide on a stud 24 fixed on said wall, but the tongue 20 isoffset from said body 21 so as to be midway between the front and backwalls 10, 11 of the padlock, as clearly seen in Fig. (3. In front ofsaid body 21 of the lock bolt lie four tumblers 25, 26, 27 and 28, theirthickness being such that the front face of the front one 28 is flushwith the front face of the lock bolt tongue 20. These tumblers are allpivoted on a common pin 29 on the back wall 11, and have individualsprings 251, 261, 271 and 281. The tumblers all have vertical slots, as282, 283 and 284, connected intermediate of their upper and lower endsby slanting slots, as 285 and 286, all said slots adapted to receive astud 30 on the lock bolt 21. It will be understood that as the lock boltis slid, the stud 30 passes from the top of one set of vertical slots,as 282, to the next, as 283, and the object of the slanting connectingslot 285 is to insure that the stud 30 cannot go too far, or into thenext connecting slot 286, but will hit the side of the vertical slot283. The key post 31 is on the back wall 11, below the lock bolt andturn blers, and the bit of the key, not shown, is adapted to raise thetumblers and slide the lock bolt, as will be understood. In thedrawings, I have shown a construction requiring two complete rotationsof the key to slide the lock bolt into fully locked or unlockedposition.

Lying flatwise against the front tumbler 28, and serving to hold saidtumblers against the lock bolt 21, or in place on their pin 29 and stud30, is a slide plate 32, parallel to the front and rear walls 10, 11 andintermediate thereof. This slide-plate is mounted upon the front wall,by means of posts 33 having reduced ends 34 riveted into said front walland opposite reduced ends 35 which enter slots 36 in the slide-plate.The slide-plate is thus adapted to move or reciprocate in the samedirection as the lock bolt, and is normally held at the left hand limitof its movement by a spring 37, as shown most clearly in Fig. 4. Thesaid slideplate 32 is apertured, as at 38, to provide ample clearancefor the key-post 31 and keyhole 39 in the front plate or'wall, no matterin what position the slide-plate may be. Around the said keyhole 39, atthe outer side of the front wall 10 of the lock casing, is a raisedframe 40, within which are hinged doors 41 and 42, adapted when closedor folded against the front wall to meet at their edges and cover thekeyhole 89, the edge of one door, as 42, having an overlap 43 to coverthe joint between the doors. Said door 42 has at its inner side acatch-member 44 which is adapted as the door is closed to projectthrough a slot 45 in the front wall into the interior of the casing. Thedoors are normally thrown into wide open position by means of leafsprings 411, 421 secured at one end to the inner side of the front wall10 and projecting through apertures 412, 422 in said front. wall topress at their free ends against the said doors.

The slide-plate 32 has a catch member 46 which is adapted to engage withor release the catch member 44 on the door 42, according to the positioninto which the slide plate is reciprocated. In normal position of theslide plate the catch members are in engagement, as shown in Fig. 7.

On the outside of the front wall 10 are knobs 47, 48 and 49, 50 arrangedin vertical pairs on opposite sides of the door frame 40. Of these knobsone, as 50, has a cylindrical stem 51 extending through a slot 52 in thefront wall, and a screw 53 is driven loosely through the slide-plate 82into said stem 51. By this means the said knob 50 will freely rotate,and yet at the same time can be pushed upon to slide the slide-plate 32against the power of its spring 37. The other knobs 47, 48 and 49 havestems which are round, as at 471, to turn in the front wall 10, andwhich beyond said round portions are squared, as at 472, 482, 492, toreceive disks 54, 55 and 56, respectively. These disks fill the spacebetween the front wall 10 and slide plate 32, being loose enough torotate freely. Furthermore, each disk is notched, as at 541, 551, or561, and adjacent to its periphery are projections 542, 552 or 562, onthe slide plate, said projection being adapted to enter said notches,respectively, when the disks are turned into proper position.

In order to enable the knobs 47, 48 and 49 to be set so that theircorresponding notched disks will be in alinement with their respectiveprojections, as shown in Fig. 4, so that the slide-plate 32 can be slidby means of the other knob 50 and the doors 41, 42 opened to expose thekeyhole, said knobs are provided at their peripheral edges withcharacters, and other characters are stamped upon the face of the frontwall 10, as is common and well known in combination locks.

To further increase the difliculties of an unauthorized person strivingto open my improved lock, I have formed the rear of the lock of exactlythe same outward construction as the front. To this end the rear wall 11has a door frame 57 in which are fixed doors, or doors which thoughperma nently closed present the same appearance as do the front doors41, 42 when closed. Also knobs 58, 59 and (30, (31 are rotatably mountedupon said rear wall 11, said knobs, however, merely having short roundstems riveted loosely into the rear wall, as shown in Fig. 7.

Having thus described the invention, what I claim is:

In a lock, the combination of a casing having a front wall with akeyhole and a hinged outer door adapted to cover said keyhole, a catchmember on the inner side of said door adapted to project through saidwall, a rear wall of similar outward construction to said front wallwith its door permanently closed, a slide plate inside said casingparallel to said walls, means slidably supporting said plate, knobsoutside the front and rear walls having stems extending rotatablythrough said walls, said knobs being similar and similarly disposed,means securing the stem of one of said front knobs to said slide-plate,the front wall being slotted for this stem, notched disks fast on thestems of the other front knobs and lying against said slide-plate,projections on said plate adapted to enter the notches, a catch memberon the slide plate adapted to engage the said catch member on the hingeddoor, and a lock bolt and tumblers between said slide plate and the rearwall.
